ABSTRACT:
There is disclosed a differential amplifier circuit wherein resistors (89, 91) and capacitors (90, 92) are connected respectively between sources of a differential pair of NMOS transistors (85, 87) and a power supply (2). The resistors (89, 91) raise the source potential of the NMOS transistors to reduce current flows during the time no transition of signal level outputted from the differential amplifier circuit occurs, reducing power consumption in the differential amplifier circuit. The capacitor (90, 92) alleviate the effects of voltage drop by the resistors (89, 91) during the signal level transition to prevent reduction in operating speed of the differential amplifier circuit.
